I got this to replace a lost sleeping bag sack. My average size mummy bag fit with a little bit of effort. It compresses the bag to about half the size and seems to be good quality. Overall happy with purchase, exactly as described.

I recently purchased a synthetic sleeping bag and while I loved the bag I did not love how much room it took up in my pack. Alps compression stuff sack to the rescue! It was easier to get the sleeping bag into than the sack it came to and reduced the overall size of the packed bag by about a third. Well made product with quality materials.

I now know that holding out a measuring tape and imagining the capacity do not convey the size like seeing it in person. This bag is very well constructed and I like the little zipper on the end to stash my inflatable pillow to keep my sleep system all together. While I was hoping to make my sleeping bag a bit smaller using the compression, I am keeping this sack since it is made well and can be used on other items.

Perfect for my 40 deg. sleeping bag. Had the original sack break a couple straps and needed a new bag, this one more than does the job. Highly recommend if you need a replacement sack. Would also work great as a gear bag as well to put into your backpack for overnights.

Question & Answer

I do not believe it is waterproof. I see no evidence of any coating on the inside of the nylon. Your best bet would be to use this stuff sack to compress your sleeping bag and then tuck it into a dry bag if you were going into really wet conditions.

It is a good question. I use this as my bear bag often. In fact, I just used it last night as my bear bag during a torrential downpour. The outside definitely gets wet and remains damp for some time afterwards. However, I've never had a case where anything inside has been more than very slightly damp. I'd call it water-resistant. This being the case, it works for me. I'd be careful how you hang it, so that you maximize the water run off.

I would say buy the large. I have down bags and the medium is more than big enough. My problem with synthetics has always been getting them in the bag to start with and I just think I would go with the large sack unless you are better at stuffing them than me.

“This is sort of a cross product question: I have the alps 0 degree echo lake bag. Will it be compressible with this compression sack? Its apparent dimensions are 80x32"”

This size should fit your bag, but it hard to say without the dimensions. It will fit most regular mummy bags, especially down. It will compress down to about 18", it just depends how tight you pull the straps.
